COMBINATION-CHAIR.

Specification of Letters Patent.

Application filed August 28, 1911.

Patented June 11, 1912.

Serial No. 646,524.

To all whom it may concern:

Be it known that I, Luis M. PETERSON, a citizen of the United States,residing at Bingham Canyon, county of Salt Lake, and State of Utah, haveinvented certain new and useful Improvements in Combination- Chairs, ofwhich the following is a specification.

This invention relates to chairs which are convertible into cots andadjustable into various positions as chairs to suit the comfort andconvenience of the user.

The object of the invention is to provide a simplified form ofconstruction of the particular type of chair to which my inventionrelates, and with this object in view the invention consists in thenovel construction, combination and arrangement of parts hereinafterdescribed in detail, illustrated in the accompanying drawing andincorporated in the appended claims.

In the drawingFigure l is a perspective View of a chair and cotcombination embodying my invention. Fig. 2 is a side elevation, partlyin section, of the chair with its back and foot rest arranged for areclining position of the user, and showing how the flexible backadjusts itself into a pillow portion.

In the several, views2/ represents the seat portion of thechair, or theframe for the seat, covered by a piece of upholstery, canvas or flexiblecovering 2, which is shown extending upwardly over a back-frame 3 as aback upholstery 3. The frame 3 of the back, which includes the rigidportion 3 and the flexible covering 3, is pivoted at 13 at the sides ofthe seat frame 2 and near its rear end. Slightly in the rear of thepivot ing 13, namely at 9, is fulcrumed at each side of the chair alever 8. The two levers 8 support the back 3 and 3 by being pivoted at12 (both sides of the chair being alike) to the sides of a strut orsupport 10 itself pivoted at 11 to the chair-backframe 3. To the frontend of the seat frame 2 is pivoted at 4 the upper end of a 1eg-rest 4,and to the lower end of the latter is pivoted at 31 a foot-rest 5. Theback, leg rest and foot rest are connected for synchronous orsimultaneous movementsof adjustment through a connecting bar 14 at eachside of the chair, the rear end of this bar being pivoted at 1 1 to thelower end of the lever 8. The forward portion of the bar is a portionthereof bent at an angle to the body of the bar and is separatelydesignated by the numeral 16. This bent portion is pivoted at itsjunction with the body of the bar, at 15, to the lower end of theleg-rest and its extreme forward end is provided with a rod or pin 17which engages a slot 18 in the edge of the foot rest. The forward legsof the chair are labeled 6 and the rear legs are labeled 7. These legsmay take any suitable and desired form of ornamentation as theirpeculiar construction is not involved in the working mechanism of thechair.

At the top of the back is a pillow-board or support 33 about which theupper end of the flexible back 3 is wrapped as shown in Fig.2. Theconstruction and arrangement of the back in connection with the pivotingof the levers 8 and strut or support 10, are such as to convert aportion of the flexible back into a pillow portion when the back islowered as in Fig. 2. This is accomplished by permitting the body of theback 3 to drop lower than that part which covers the pillow support 33.At the bend in the flexible portion 2 and 3, or where the horizontalportion joins the back portion, along, say, the axis of 13 or 9 there isa tendency to take up slack by the bending of the flexible covering 2'and 3 in raising the back from reclining position to upright position.Again by comparing Figs. 2 and 1 it will portion 3 are broughtsubstantially into alinement. These supports are cross-pieces or slats 8between the levers 8 and the pillow-support 33 on the back-frame 3. InFig. 2 the pivots 11 and 12 are alined on a line at substantially rightangles to the plane of the back and the levers 8, while in Fig. 1 thesepivots are on a line substantially parallel to the back. In this mannerthe automatic pillow adjustment is effected without providing anyspecial mechanism or parts and by the mere manner in which the levers,back and back support 10 are pivoted together.

A mechanism for supporting the adjustable parts in their adjustedposition with the aid of the above-described connections, isarranged-underneath the seat or chair bottom 2 and 2 and consists of asuitably be noted that the supports for the flexible mounted transverseshaft 29 which may be rocked by a short lever 30 arranged on one of theends of the shaft. To the respective ends of this shaft are keyed a pairof arms 27 and 28. To thefree ends of these arms are pivoted the upperends of connecting rods 25 and 26 and the lower ends of the latter are,in turn, pivoted to the rear ends of a pair of quadrants 19 and 20pivoted forwardly to the foot. or leg rest at 21 and 22 and havingnotches 2a therein. These notches are adapted to engage a rod 23 mountedin and between the chair-legs 6. Thus by simply pulling backward on thelever or handle 30 the notches 24: in engagement with the rod 23 will bereleased from said rod. The leg and foot'rests will then, together withthe back, be free to swing on their respective pivots into horizontalpositions and make the whole structure a bed or cot. As the back islowered the levers 8 are caused to travel in advance of the backframe 3until when the Fig. 2 position is reached the head rest is as muchhigher than the support 8 for the balance of the flexible back, as thedistance between the pivots 11 and 12, which distance may, of course, bevaried to individual requirements. In the Fig. 2 position the distancefrom the center 13 to the points 11 and 12 is substantially the same,but in raising the parts of the back from this position the levers 8swing about the center 9 while the back frame 3 swings about the center13 and describes a larger arc. The result is that in the raised positionthe flexible part 3 of the back is stretched to the eXtent'of thedistance between centers 13 and 9. In other words the head-rest 33 is inthe upright position of the back substantially raised to the extent ofthe distance between the centers 13 and 9. This opera tion of stretchingthe raised back is supplemented by the substantial alining of the rearsupports for the flexible part 3. This provision which places thepillow-end of the back higher than the body of the back, when the latteris lowered, is accomplished without the use of any additional mechanismfor that purpose other than that employed for automatically placing therest 10 in a vertical position under the back when the latter isinclined as in Fig. 2. This automatic or positive movement of the back10 insures its proper position and obviates the risk of a looselypivoted support 10 of the latter taking a position, or beingaccidentally positioned, at such an angle as to make the supportinsecure, or as to permit the back to drop to the floor.

It will be noted that the levers 8 are in such position that they maycover the edges of the back as a whole, or form side-pieces, as it were,for the back-portion 3. In such capacity their outlines may be adapted,for the sake of appearances, to whatever design may be desired for thechair-back. Such ornamental features are purposely avoided in thedrawing for the sake of more clearly distinguishing the different parts.The position of the side-bar 14 at each side is also such as to simulatea part of the ordinary chair construction, such as the ordinary round,brace, or connecting bar between the front and rear leg at each side.

For a rearward inclination of the back, short of the inclination shownin Fig. 2,

. the back has very firm support in the double pivoting thereof at 9 and13 and the positive engagement of the notches with the bar 23. Havingthus described my invention, I claim as new and desire to secure byLetters Patent 1. The combination with a chair-seat and its supports orlegs, of a back-frame pivoted to said seat, a head-rest mounted at theupper end of said back-frame, a leg-rest pivoted to said seat, afoot-rest pivoted to said legrest, connections between said backframe,leg-rest and foot-rest which move said leg-rest and back-frame angularlyand said foot-rest parallel to said seat when said back-frame is swungpivotally, a flexible covering on saidseat, back-frame and headrest, astrut-support for said back frame, means for maintaining its normallysuspended or substantially vertical position throughout the movements ofsaid pivoted parts, and means for locking all of the said pivoted ormovable parts against movement.

2. The combination with a chair-seat and its supports, of a back-framehavinga headrest thereon, said back-frame pivoted to said seat fortilting movement relative thereto, a flexible covering for said seat,back-frame and head-rest, a strut-support pivotally suspended 011 saidback-frame at substantially the lower edge of said head-rest, a leg-restpivotally suspended from said seat, a footrest pivoted to said leg-rest,a pair of levers pivoted to said strut-support and to said seat,connecting-bars pivoted to said levers and .to said leg-rest andfoot-rest, said levers supporting said foot-rest in its horizontalposition throughout its movements and also supporting said strut-supportin its vertical suspended position, the I pivoting of said strut-supportto said, levers being below the pivoting thereof to said back-frame,whereby a pillow-offset is formed between the levers and head-rest, andslats 8 on said levers for supporting the back-portion of said flexiblecovering below the plane of said head-rest when said back-frame istilted into a horizontal position. 4

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
